Baytown is a city within Harris County and partially in Chambers County in the Gulf Coast region of the U.S. state of Texas. Located within the Houston–Sugar Land–Baytown metropolitan area, it lies along both State Highway 146 and Interstate 10. As of 2006, Baytown had an estimated population of 78,311. It is the fourth-largest city within the metropolitan area.
The area of Baytown began to be settled as early as 1822. One of its earliest residents was Nathaniel Lynch, who set up a ferry crossing at the junction of the San Jacinto River and Buffalo Bayou. The ferry service that he started is still in operation today, now known as the Lynchburg Ferry. Other early residents of Baytown include William Scott, one of Stephen F. Austin's Old Three Hundred, and Ashbel Smith, who owned a plantation in the area.
The city now known as Baytown was originally three separate towns. The first of these was Goose Creek, named for the bayou of the same name where Canada Geese wintered and whose name is still reflected in the area's Goose Creek CISD, whose establishment dates back to before 1850. With the discovery of the Goose Creek Oil Field, the rival communities of Pelly in the late 1910s, and East Baytown in the early 1920s, developed as early boomtowns. The "East" in East Baytown was later dropped because it was west of Goose Creek.
